private void Form1_Load(object sender, System.EventArgs e

System.Windows.Forms.TabPage tabPage = new TabPage()
tabPage.Text = "Page 1"
this.tabControl1.TabPages.Add(tabPage)
tabPage = new TabPage()
tabPage.Text = "Page 2"
this.tabControl1.TabPages.Add(tabPage)
this.tabControl1.TabPages.RemoveAt(0)
MessageBox.Show(this.tabControl1.TabPages[0].Text)


Run the program. (I'm running on a Dell Axim device with Pocket PC version 4.20.1081 and .NET CF 1.0 Service Pack 2
You will see a crash when the Message Box is shown. (I would expect to see "Page 2"

I tried to do the same in a Windows Application, which works fin

Am I doing something wrong here?
Is this a bug?
Is there a work around for this problem? (My application needs to Add and remove TabPages in Run time

Thanks for your help
